When doing a recursion like this:

function foo ()
{
  foo ();
}

php crashes after a few thousand recursions. The number of recursions
possible depends on the function size. I recompiled the webserver without optimization and debugging symbols accordingly.

Program received signal SIGSEGV, Segmentation fault.
0x2822f7bb in object.11 () at ./zend_execute.c:877
877     }
(gdb) bt
#0  0x2822f7bb in object.11 () at ./zend_execute.c:877
Error accessing memory address 0xbbbffc3c: Bad address.

Oh btw, I'd appreciate to see a password field for passwords in the bug form...

This is not a bug. PHP currently does not handle infinite recursions.
